Notes on chip component replacement• Never reuse a disconnected chip component.• Notice that the minus side of a tantalum capacitor may be
damaged by heat.
Flexible Circuit Board Repairing• Keep the temperature of the soldering iron around 270 ˚C
during repairing.• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).• Be careful not to apply force on the conductor when soldering
or unsoldering.
CAUTIONUse of controls or adjustments or performance of proceduresother than those specified herein may result in hazardous radiationexposure.
UNLEADED SOLDERBoards requiring use of unleaded solder are printed with the lead-free mark (LF) indicating the solder contains no lead.(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size)
: LEAD FREE MARKUnleaded solder has the following characteristics.
• Unleaded solder melts at a temperature about 40 ˚C higherthan ordinary solder.Ordinary soldering irons can be used but the iron tip has to beapplied to the solder joint for a slightly longer time.Soldering irons using a temperature regulator should be set toabout 350 ˚C.Caution: The printed pattern (copper foil) may peel away if
the heated tip is applied for too long, so be careful!• Strong viscosity
Unleaded solder is more viscou-s (sticky, less prone to flow)than ordinary solder so use caution not to let solder bridgesoccur such as on IC pins, etc.
• Usable with ordinary solderIt is best to use only unleaded solder but unleaded solder mayalso be added to ordinary solder.
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINEWITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND INTHE PARTS LIST ARE CRITICAL TO SAFE OPERATION.REPLACE THESE COMPONENTS WITH SONY PARTS WHOSEPART NUMBERS APPEAR AS SHOWN IN THIS MANUAL ORIN SUPPLEMENTS PUBLISHED BY SONY.
ATTENTION AU COMPOSANT AYANT RAPPORTÀ LA SÉCURITÉ!
LES COMPOSANTS IDENTIFIÉS PAR UNE MARQUE 0 SURLES DIAGRAMMES SCHÉMATIQUES ET LA LISTE DESPIÈCES SONT CRITIQUES POUR LA SÉCURITÉ DEFONCTIONNEMENT. NE REMPLACER CES COM- POSANTSQUE PAR DES PIÈCES SONY DONT LES NUMÉROS SONTDONNÉS DANS CE MANUEL OU DANS LES SUPPLÉMENTSPUBLIÉS PAR SONY.
SAFETY CHECK-OUTAfter correcting the original service problem, perform the followingsafety check before releasing the set to the customer:Check the antenna terminals, metal trim, “metallized” knobs, screws,and all other exposed metal parts for AC leakage.Check leakage as described below.
LEAKAGE TESTThe AC leakage from any exposed metal part to earth ground andfrom all exposed metal parts to any exposed metal part having areturn to chassis, must not exceed 0.5 mA (500 microamperes.).Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCAWT-540A. Follow the manufacturers’ instructions to use theseinstruments.
2. A battery-operated AC milliammeter. The Data Precision 245digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of aVOM or battery-operated AC voltmeter. The “limit” indicationis 0.75 V, so analog meters must have an accurate low-voltagescale. The Simpson 250 and Sanwa SH-63Trd are examplesof a passive VOM that is suitable. Nearly all battery operateddigital multimeters that have a 2 V AC range are suitable. (SeeFig. A)

SERVICING NOTES
NOTES ON HANDLING THE OPTICAL PICK-UPBLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostaticbreak-down because of the potential difference generated by thecharged electrostatic load, etc. on clothing and the human body.During repair, pay attention to electrostatic break-down and alsouse the procedure in the printed matter which is included in therepair parts.The flexible board is easily damaged and should be handled withcare.
NOTES ON LASER DIODE EMISSION CHECKThe laser beam on this model is concentrated so as to be focused onthe disc reflective surface by the objective lens in the optical pick-up block. Therefore, when checking the laser diode emission,observe from more than 30 cm away from the objective lens.
LASER DIODE AND FOCUS SEARCH OPERATIONCHECKCarry out the “S curve check” in “CD section adjustment” and checkthat the S curve waveforms is output three times.

CD SECTION
Note:1. CD Block is basically designed to operate without adjustment.
Therefore, check each item in order given.2. Use YEDS-18 (3-702-101-01) unless otherwise indicated.3. Use an oscilloscope with more than 10MΩ impedance.4. Clean the object lens by an applicator with neutral detergent when the
signal level is low than specified value with the following checks.• Abbreviation
MX: Mexican model
S-CURVE CHECK
Procedure:1. Connect an oscilloscope to TP (FE) and TP (VC) on the CD
board (except MX) or BD board (MX).2. Press the I/1 button to turn the power on.3. Load the disc (YEDS-18) and actuate the focus search. (In
consequence of open and close the disc tray, actuate the focussearch)
4. Confirm that the oscilloscope waveform (S-curve) issymmetrical between A and B. And confirm peak to peak levelwithin 3 ± 0.5 Vp-p.
Note: • Try to measure several times to make sure than the ratio of A : Bor B : A is more than 10 : 7.
• Take sweep time as long as possible and light up the brightnessto obtain best waveform.
Connecting Location: CD board (except MX)BD board (MX)
RFAC LEVEL CHECK
Procedure:1. Connect an oscilloscope to TP (RFACO) and TP (VC) on the
CD board (except MX) or BD board (MX).2. Press the I/1 button to turn the power on.3. Load the disc (YEDS-18) and playback.4. Confirm that oscilloscope waveform is clear and check if RFAC
signal level is correct or not.Note: Clear RFAC signal waveform means that the shape “ ◊ ” can be clearly
distinguished at the center of the waveform.
